Select all of the equations below that are equivalent to: x + 9 = 11 Use properties of equality. Multi-select Choices: (A)x + 9 − 6 = 6 (B)x + 9 − 6 = 5 (C)x + 9 − 3 = 9 (D)x + 9 − 4 = 6

Simplify equation: Simplify the original equation to find x; x + 9 = 11. Subtract 9 from both sides to isolate x: x = 11 - 9. Calculate x: Calculate x: x = 2. Check choices: Check each choice by substituting x = 2 and simplifying: (A) 2 + 9 - 6 = 5, which simplifies to 5 = 5.

Identify equivalent equations

Full solution

Q. Select all of the equations below that are equivalent to:

\newline

x + 9 = 11

\newline

Use properties of equality.

\newline

Multi-select Choices:

\newline

(A)

x + 9 - 6 = 6

\newline

(B)

x + 9 - 6 = 5

\newline

(C)

x + 9 - 3 = 9

\newline

(D)

x + 9 - 4 = 6

Simplify equation: Simplify the original equation to find $x$ ; $x + 9 = 11$ . Subtract $9$ from both sides to isolate $x$ : $x = 11 - 9$ .
Calculate x: Calculate x: $x = 2$ .
Check choices: Check each choice by substituting $x = 2$ and simplifying: $\newline$ (A) $2 + 9 - 6 = 5$ , which simplifies to $5 = 5$ .
